# Common Mathematica Keyboard Shortcuts

This is not an exhaustive list, just the ones that we are likely to use in our class work. These work in Windows. If you have some other operating system (Mac or Linux), consult the Mathematica Help.

Ctrl means the control key (hold it down and keep it down while you type the other characters).

Esc means the escape key (press and release Esc, type in the other characters, then press and release Esc again).

To make: Type the following:
exponent Ctrl 6
fraction Ctrl /
square root Ctrl 2
other root (cube root etc.) Ctrl 25
π Esc p Esc
The number e Esc ee Esc
or use a capital E
θ Esc th Esc
infinity Esc inf Esc
an arrow (like you need for PlotStyle) Esc - > Esc
(Don't need the escape if you are in an input cell. Just type - > and keep going, and it will turn into an arrow.)
double equal sign (like you need for Solve) Esc = = Esc
(Don't need the escape if you are in an input cell. Just type two equal signs and keep going.)
Not equal sign Esc ! = Esc
(Don't need the escape if you are in an input cell.)
less than or equal sign Esc < = Esc
(Don't need the escape if you are in an input cell.)
greater than or equal sign Esc > = Esc
(Don't need the escape if you are in an input cell.)
Indefinite integral Esc intt Esc
Definite integral Esc dintt Esc
summation (sigma notation) Esc sumt Esc

You can see keyboard shortcuts for many of the other characters on the symbol palette by holding the mouse over the character that you want. (Look along the bottom of the palette for the corresponding shortcut.)

Another very useful keyboard shortcut is Ctrl l (that's a lower case L), which automatically makes a copy of the previous input cell (relative to wherever the cursor is located) without having to highlight anything.
